Using the data given in Example 15.2, calculate [N₂O₅] 150. s after the start of the reaction.

Data from Example 15.2

The decomposition of N₂O₅ in the gas phase was studied at constant temperature:

The following results were collected:

Using these data, verify that the rate law is first order in [N₂O₅], and calculate the value of the rate constant, where the rate = –d[N₂O₅]/dt.
